i am new to react and trying to learn it by myself , i am facing problem in navigating user back to root screen from nested stck navigator screen .
Here is some of m
As per react navigation doc you can go to any stack by following ways: check the following link for more details React-navigation stack action link
1. import { StackActions, NavigationActions } from 'react-navigation';
const resetAction = StackActions.reset({
index: 0,
actions: [NavigationActions.navigate({ routeName: 'Profile' })],
});
this.props.navigation.dispatch(resetAction);
import { NavigationActions } from 'react-navigation';
const navigateAction = NavigationActions.navigate({
routeName: 'Profile',
params: {},
action: NavigationActions.navigate({ routeName: 'SubProfileRoute' }),
});
this.props.navigation.dispatch(navigateAction);
(React Navigation 5.x) I had the problem of conditionally rendering the Screens like the example in "https://reactnavigation.org/docs/en/auth-flow.html" As I understand, meant that the Stack navigators were not "rendered" and thus are not able to find each other. What I did was the below and in the logout page:
navigation.replace('SplashScreen')
My logic was: SplashScreen (Check for AsyncStorage Token),
if (token){
navigation.navigate('App')
}else{
navigation.navigate('StartScreen')
}
In StartScreen, just navigate to Signin or Register where you go back to App if login is successful.
As a reference,
function AppBottomNavigator(){
return(
<AppNavigator.Navigator
initialRouteName={'Home'} ...}>
<AppNavigator.Screen name='A' component={ScreenA}/>
<AppNavigator.Screen name='B' component={ScreenB}/>
<AppNavigator.Screen name='C' component={ScreenC}/>
<AppNavigator.Screen name='D' component={ScreenD}/>
<AppNavigator.Screen name='E' component={ScreenE}/>
</AppNavigator.Navigator>
)
}
export default App stuff...
...return(
<AuthContext.Provider value={authContext}>
<NavigationContainer>
<AuthStack.Navigator screenOptions={{headerShown:false}}>
<>
<AuthStack.Screen name='SplashScreen' component={SplashScreen}/>
<AuthStack.Screen name='StartScreen' component={StartScreen} />
<AuthStack.Screen name='SignIn' component={SignIn} />
<AuthStack.Screen name='Register' component={Register} />
<AuthStack.Screen name='App' component={AppBottomNavigator}/>
</>
</AuthStack.Navigator>
</NavigationContainer>
</AuthContext.Provider>
)
I am also quite new to this but it worked so if someone else has a safer/tidier/general solution, I would quite like to know, too.
After trying almost everything, I've found the solution that worked for me:
this.props.navigation.popToTop(); // go to the top of the stack
this.props.navigation.goBack(null); // now show the root screen
Requires: react-navigation
version: 1.0.0
Goal: Navigate from App
TabNavigator to Screen 1
to Screen 2
to Screen N
and then directly back to App
TabNavigator.
StackNavigator {mode: 'modal'}

The solution was to add key: null
to the reset object:
this.props.navigation.dispatch(NavigationActions.reset({
index: 0,
key: null,
actions: [
NavigationActions.navigate({ routeName: 'App'})
]
}))
I was tipped off by this comment.
(FYI - I got here via your comment asking for help.)
